Large-scale livestock operations face a big challenge: how to
handle all the manure the animals produce. Manure spills and runoff can
contaminate water with nitrogen and phosphorous. The result can be
polluted drinking water, or fish kills in streams and lakes. But now,
Purdue University researchers have found a way to significantly lower
the
pollutants in hog manure. The Great Lakes Radio Consortium’s Wendy

Commentary – Epa Misses an Opportunity
Last month (April) the U.S. Environmental Protection Agency decided
against regulating ash and sludge from coal-burning power plants as a
toxic hazardous waste. Instead, the EPA will develop voluntary coal-ash
disposal standards. Great Lakes Radio Consortium commentator Suzanne
Elston says the move is a major setback in the war against global
warming:
Educating Parents About Mercury
Over the years, parents have become more aware of the dangers
in their own homes. So they keep kids away from things like pesticides,
electrical cords, and plastic bags. Still, most people remain unaware of
another threat from a common household item. Ironically, it may be the
first thing you reach for when your child is sick. The Great Lakes Radio
Consortium’s Wendy Nelson reports:

Genetically Altered Trees Eat Mercury
In an article in the journal "Nature Biotechnology" researchers saythey’re developing plants that clean up mercury contamination. TheGreat Lakes Radio Consortium’s Lester Graham reports:
Inner-City Children and Lead Exposure
Many inner-city homes built before World War Two still contain lead paint-making them harmful environments for children. An estimated twenty-percent of inner-city children have dangerous levels of lead that could be hampering their central nervous systems. Researchers are trying to find out what long-term effects lead exposure in the home has on children. And they’re testing a drug that might reverse those effects.

D-D-E May Degrade Naturally
The notorious pesticide D-D-T was banned in the United States in the 1970’s. But D-D-T left behind several toxic byproducts. One of those is D-D-E. However, a new study published in this month’s Science magazine suggests that D-D-E may be decaying naturally. The Great Lakes Radio Consortium’s Steve Frenkel reports:
